It should be understood that the invention is not restricted solely tothe details of construction of the form described above, which may bemodified in various ways without departing from the scope of theinvention. For instance, instead of assembling the part b and the plate(1 by means of dovetailed bevelling of the edges, any other form ofmutually positioning the parts, such as a prismatic arrangement, may beadopted. It' is not necessary for the part e to projectdownwardly fromthe plate at, and if it does not project in the manner shown theassembly and location of the plate d relatively to the part b may beeffected by means of abutments or bevels on the top or bottom edges ofthe rectangular aperture of the member b and/or the plate d. The parts 0and d are not necessarily rectangular, but may be given any otherpreferred shape, as desired.

Having described my invention, I declare that what I claim and desire tosecure by Letters Patent is:-

1. A spaceband for a matrix composing and type line casting machinecomprising relatively movable members, wherein one of said members isformed of parts having suitably shaped portions to be detachablyassembled by interfitting engagement and being adapted to be heldtogether by their assembly with the other member to form, the completespaceband.

2. A spaceband for a matrix composing and type line casting machinecomprising three parts detachably connected, two of said parts beingshaped to fit together and be movable, as a unit, relatively to theotherpart and being held together by their assembly with said other part toform the complete spaceband.

3. A spaceband for a matrix composing and type line casting machinecomprising a long wedge member, having a dovetailed groove, a shorterwedge member, and a separate connecting piece associated with theshorter member by interfitting engagement therewith and having adovetailed guide for engaging said dovetailed groove to hold said longand shorter wedge members in movable relation, said members andconnecting piece being held together by their interfitting engagementwith one another.

4. A spaceband according to claim 3, wherein said shorter wedge memberis apertured, said connecting piece extending through said aperture sothat the dovetailed guide projects beyond one side of the shorterwedge'member, said connecting piece being adapted to prevent removal ofthe shorter wedge member laterally away from the longer wedge memberwhen the spaceband is assembled.

5. A spaceband for a matrix composing and type line casting machinecomprising a long Wedge member with, a longitudinal dovetailed groove, ashorter wedge member having an aperture with bevelled edges, and aremovable con- 7 necting piece having a dovetailed guide on one sideadapted slidably to engage in said dovetailed groove, said connectingpiece being adapted to fit into said aperture and having bevelled edgescor-' bination, a pair of relatively movable comp1e mentary wedge-shapedmembers presenting inner surfaces in bearing contact, and a removableconnecting'element having a tight fitting tongue and groove connectionwith one member and a sliding connection with the other member to holdthe members against facewise movement.
